IIWPROVEMEN T IN LUBRICATORS.

The Schedule referred tp in these Letters Patet and making part of the vname To all whom it ma/y concern Be it known that we, M. BERGNER and OTTO NET- zow, of the city and county of Baltimore, and State of Maryland, hare invented a new and useful Improvement in Lubricators for Car-Axles, Shafting, 8m.; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a transverse vertical section.

Figure 2 is a longitudinal vertical section.

The nature of our invention consists in a peculiar arrangement of parts, by which a shaft or axle may be constantly supplied with a suficient quantity of lubrieating-oil without perceptibly increasing the amount of friction, and at the same time may be kept clean and free from dust and dirt.

To enable others skilled in the art to which our invention appertains, to make and use the same, we will proceed to describe its coustructionand operation.

In the drawings- A represents the journal of a car or other axle,'and

B, the journal-box in which it Works.

i C is a block, which 'forms a bearing-surface for the journal, and may be faced with brass, Babbit metal, or other suitable material.

D is an oil-chamber, divided into two compartments, E E, which are separated by partitions e e, said partitions being perforated, so as to allow the escape of oil from the compartments E E, and being a suliicient distance apart to admit the device for supplying oil to the journal.

Said device consists of a plate, F, of suitable material, covered with a fibrous fabric, f, woven in a manner and form similar to the wick of an argand lamp, so as to surround said plate longitudinally, said plate and fibrous substance working freely in the space between the perforated partitions e e, and being kept constantly in contact with the journal by means of `a spring, H, which rests upon the bottom ofthe space between the partitions c c, and the tension of which is just suliicient to cause a gentle but constantpressure of the brous material against the journal.

The fibrous material, or wick j, acting by capillary attraction, draws the oil from the chambers E E, and, being kept constantly in contact with the axle, it keeps the axle constantly supplied with oil.

The said wick f being Woven in the form hereinbefore described, and surrounding the plate F longitudinally, said wick can be occasionally turned, so as to present a fresh portion to the axle, thus preventing it from being worn through by friction.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is

The construction and arrangement of the journalbox, having the double-chambered oil-box E E, with perforated partitions c e, between which slides the wickholder F, 'bearing the adjustable wick f, the holder F being supported by the spring H, all as shown and described. y
